2 Claims. (Cl. 30-605) This invention relates to a safety razor and hasfor its primary object to releasably hold a razor blade in the head ofthe safety razor without requiring the use of screw threads or the likein the razor construction.

Another object is to resiliently hold the movable clamping jaws of thesafety razor in clamping engagement with the blade thereof and at thesame time facilitate the rapid opening of the jaws for permitting theinterchanging of the blades of the razor.

Another object is to releasably hold the jaws out of clamping engagementwith the blade during the interchanging of the blades.

A still further object is to afford adjustment of guards relative to thecutting edges of the razor blade and to enable guards of different typesto be employed.

The above and other objects may be attained by employing this inventionwhich embodies among its features in a safety razor of the type havingstationary blade supporting jaws and blade clamping jaws carried by thestationary jaws for movement about parallel axes adjacent the edges ofthe stationary jaws, a plunger movable between the stationary jaws andoperatively connected with the movable jaws for moving the movable jawsinto clamping engagement with a safety razor blade mounted on thestationary jaws, and a spring engaging the plunger to yieldingly advanceit away from the stationary jaws to hold the movable jaws into clampingengagement with a razor blade supported on the stationary jaws.

Other features include a push button for moving the plunger against theefiort of the spring to open the clamping jaws and facilitate thechanging of razor blades, and releasable means for holding the plungeradvanced against the effort of the yielding means.

In the drawings:

Figure l is a perspective view of a safety razor embodying the featuresof this invention;

Figure 2 is a top plan view of the razor illustrated in Figure 1;

Figure 3 is a transverse sectional view taken substantially on the line3-3 of Figure 2;

Figure 4 is an end view of the razor showing the blade clamping jawsopen; and

Figure 5 is a fragmentary perspective view of a mod].- fied form ofguard.

Referring to the drawings in detail, a tubular handle is providedadjacent one end with an interior shoulder 12 and carried by theadjacent end of the handle are outwardly extending stationary bladesupporting jaws 14 carrying adjacent their outer ends depending arms 16in which are pivotally supported movable blade clamping jaws 18 whichmove in intersecting arcuate paths about spaced parallel axes onopposite sides of the handle 10. The structure so far defined isconventional with certain types of safety razors in which the blades areinterchangeable without separating the head from the handle.

Mounted for longitudinal sliding movement through the interior of thehandle 10 is a plunger 20 carrying adjacent its end which projectsthrough the end of the handle 10 adjacent the stationary jaws 14 with across head 22 which is operatively connected to the movable jaws 18 sothat as the plunger moves longitudinally within the handle 10, the jaws18 will be moved about the spaced parallel axes previously referred to.Carried by the plunger 20 and extending through the end of the handle 10remote from the stationary jaws 14 is a push ice button 24 having anannular groove 26 extending therearound which defines a shoulder 28, thepurpose of which will hereinafter appear. Pivotally mounted as at 30 inthe handle 10 adjacent the end thereof remote from the stationary jaws14 is a latch 32 having a tongue 34 WhlCh is urged toward the pushbutton 24 under the mfluence of a torsion spring 36 so that when thepush button is pressed inwardly relative to the handle, the tongue 34will engage the shoulder 28 to hold the cross head 22 projected beyondthe opposite end of the handle 10. Extending through the plunger 20intermediate the ends thereof is a cross pin 38, and surrounding theplunger 20 between the cross pin 38 and the shoulder 12 1s a compressioncoil spring 40 which exerts yielding pressure on the plunger 20 in adirection to hold the movable clamping jaws 18 in clamping engagementwith the razor blade B resting on the stationary jaws 14. It will thusbe seen that the razor blade B will be clamped in place under theinfluence of the spring 40 and cannot be released until pressure isexerted on the push button 24 to move the plunger 20 against the effortof the spring 40 and the jaws 18 about the spaced parallel axes.

Carried by the movable jaw members 18 and extending outwardly fromopposite ends thereof in substantial parallel relation thereto aresupporting sleeves 42 carrying set screws 44 which extend into thesleeves 42 in perpendicular relation thereto. In one form of theinvention a guard designated generally 46 comprising a supporting bar 48carrying adjacent opposite ends arms 50 is mounted on each jaw 18 byentering the arms 50 into the sleeves 42 and tightening the set screws44 to hold the bar 48 at a selected distance from the edge of a razorblade clamped between the jaws 14 and 18. In this type of guard the bar48 is provided between the arms 50 with roller disks 52 which serve asguards for the adjacent edges of the razor blade B and owing to the factthat they are rollers, the gliding of the razor over the face isfacilitated.

A modified form of guard designated generally 54 comprising a solidguard bar 56 carrying outwardly extending arms 58 may be employed inplace of the guard 46 by extending the arms 58 through the sleeves 42and securing them therein by set screws 44.

In use, it will be evident that the clamping jaws 18 will be held inclamping relation to the stationary jaws 14 under the influence of thespring 40 and when it is desired to insert or remove a razor blade Bfrom the razor, pressure is exerted on the push button 24 to move theplunger 20 against the elfort of the spring 40 and the clamping jaws 18in the position illustrated in Figure 4. With the jaws 18 in thisposition, a blade B within the razor may be readily extracted and a newone substituted therefor and upon exerting pressure on the latch 32, itwill be moved against the effort of the torsion spring 36 to extract thetongue 34 from the groove 26 and move it out of engagement with theshoulder 28 to enable the plunger 20 to move under the influence of thespring 40 and close the clamping jaws 18 on the blade to clamp itagainst the supporting jaws 14.

From the foregoing, it will be obvious that the blade may be easily andquickly removed from the razor and a new blade substituted with but aminimum of elfort on the part of the user.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.
